OIL-BURNER.

Specification of Letters Patent.

Application filed August 20, 1910.

Patented Jan. 10, 1911. Serial No. 578,231.

To all whom it may concern:

Be it known that I, HENRY J. HENNINGS, a citizen of the United States, residing at San Gabriel, in the county of Los Angeles and State of California, have invented a new and useful Oil-Burner, of which the following is a specification.

This invention relates to oil burners, and one of the main objects of the present invention is to produce a device of the character described of simple construction, economical in operation and which may be positioned in fire boxes of various sizes and shapes.

Other objects and advantages will appear hereinafter in the following description.

Referring to the drawings which are for illustrative purposes only: Figure 1 is a vertical longitudinal sectional view through a fire box of a stove having a burner therein embodying the invention. Fig.2 is a sectional plan view on line 00 -03 Fig. 1, showing the burner in plan view. Fig. 3 is a transverse sectional view on line 00 w Fig:

1. Fig. 4 is a plan view of a portion of the spreader plate.

1 designates the front wall and 2 the side walls of an ordinary cooking stove having a fire box 3 lined with fire brick 4, a grate 5, chimney flue 6 and air supply 7 regulated by means of a sliding valve plate 8, all of which are of the form in common use. The top 9 of the stove is provided with the usual pot holes 10 having suitable cover plates 11.

The burner oonslsts of two tubular superheaters 12 similar in form, each having a separate connection to a general oil supply pipe 13 which is connected to an oil reservoir or tank (not shown) situated at adistance from the stove and elevated a sulficient height above the burner to cause the oil therein to be fed to the burner by gravity.

Each superheater 12 consists of a tubular member 14. In the form shown a section of pipe is used having the outer end closed by a cap or head 15, the inner end or head 16 of each superheater being connected to the general oil supply pipe in the following manner: Entering the fire box 3 of the stove through the front wall 1 and fire brick 4 are two pipes 17, each provided with a needle valve 18 for the regulation of the flow of oil to the burner. Connected to each pipe 17 by elbows 19 is a longitudinally disposed pipe 20 and cross pipe 21.

The pipes 17 20 and 21 lie in the same plane and rest upon the grate The superheaters or tubular members 14 are elev In the top of each superheater 14 is a small orifice or outlet 27 placed in the superheater in position to come below the hole 10 of thestove. Above the superheaters 14 is a spreader plate 28 supported on nuts 29 on threaded standards or pins 30 which are received by perforations 31 in the plate 28, each pin 80 being secured in the head 16 of a superheater thereunder. The spreader plate 28 may be raised or lowered to regulate the quality of the flame by adjusting the nuts 29 on the pins 30 or by removing or adding washers 32 between the nuts 29 and plate 28. The spreader plate 28 also performs the function of fixing the superheaters in relative position to each other.

The device is operated in the ordinary manner: The needle valves 18 are opened permitting oil to flow from the supply pipe 13 through the pipes 17 and connections heretofore specified to the superheaters 14 until the oil flows out of the outlets 27 in the superheaters. The needle valves 18 are then closed and the oil at the outlets 27 lighted. The burning of the oil produces sufiicient heat to start the generation of gas in the super-heaters which burns as it escapes through the outlets 27, and the needle valves 18 are then opened a sufiicient distance to permit a supply of oil to flow to the superheaters. The flame strikes the spreader plate 28 and mixes with the air in the fire box. The supply of air is regulated by the slidin valve plate 8, the mixture of the gas and a1r being further modified by the relative height of the spreader plate above the superheaters. The oil supply connections in the fire box being below the flame results in the oil being gradually gasified as it travels from the pipes 17 to the superheaters, and, being out of the flame, have a greater life and do not need renewing for a A the superheaters have been placed at the required'height the spreader plate 28 is placed on the pins 30, a series of perforations 31 per-side thereof, a standard on each superbeing provided in the spreader plate for that purpose.

The above operation of raising or lowering the superheaters also results in bringing the superheaters closer together or farther apart, which may be done for the purpose of bringing the flames from the superheaters under the openings in the top of the stove. It is understood that only one of the superheaters may be used or that the second superheater .may be lighted after one superheaterhas been burnmg. In that case, it is only necessary to open the needle valve of the second .superheater a sufiicient distance to permit a small flow of oil to the super heater which would be gasified during the flow from the pipe 17 to the superheater and the gas emerging from the outlet in the superheater would light from the flame of the first superheater. It is understood that the flame of the first superheater would heat the 35 second superheater and inlet pipes leading thereto sufiiciently to gasify the oil flowing therethrough, producing a gas which would light from the flame of the first superheater when the gas so formed in the pipes leading to the second superheater flows from the outlet in the second superheater.

What I claim is:

I. An oil burner comprising a plurality of superheaters in the same horizontal, plane, each superheater having an outlet in the upheater extending upwardly therefrom, and means engaging said standards to retain the superheaters in relative position.

2. An oil burner comprising a plurality of superheaters in the same horizontal plane, each superheater having an outlet in the upper side thereof, a standard on each superheater extending upwardly therefrom; and a spreader plate supported on said standards, said spreader plate having a series of perforations therein to receive said standards and prevent longitudinal displacement of the superheaters.

3. An oil burner comprising a plurality of superheaters arranged in the same horizontal plane, an oilsupply pipe, oil inlet pipes between each superheater and the oil supply pipe, one of the oil-inlet pipes for each superheater being diagonally disposed and. forming vertically adjustable support for the superheater, and means above the superheaters for holding .said superheaters in the same relative posltion.

4. An oil burner comprising a pair of tubular superheaters arranged in alinement in the same horizontal plane, each of said superheaters having an outlet in the upper side thereof, an oil supply pipe, oil inlet pipes connecting said oil supply pipe to the superheaters, means for regulating the flow of oil through the oil inlet pipes, one of the oilinlet pipes for each superheater being diagonally disposed and forming v vertically adjustable support for the superheater, a standard on each superheatenand a spreader plate above said superheaters mounted on the standards and provided with a series of perforations in the spreader plate to receive each standard.

In testimony whereof, I have hereunto set my hand at Los Angeles California, this 13th day of August, 1910.
